A chat with buddy techno Kumar...
Me: hi
buddy…Whats up??
Techno Kumar: nothing …just as
usual…u say
Me : so how is your new venture
going ?? Everything okay?
Techno kumar : fine ..I am
planning to install the ERP system in my company..but since I have very little knowledge about it ..i had to
outsource the entire implementation of it..
Me: ahhh ..that`s great ..ERP
will go a long way in ensuring flexibility to your company operations..
Techno kumar: yeah I know …. but
the thing is if only I had some knowledge about what it is ..then I would not
have a problem…you know ..like for clarity and satisfaction..
Me : okay ..i understand ..i
think you MUST have an idea about the
basics of systems architecture ..that can throw some light on what work you are
doing ..
Techno kumar: is it ?? …but how
..
Me : arre main hoon na….i can
impart some knowledge on this systems architecture..but are you free now
??..because it may take some time..
Techno kumar: ..ohh ..not an issue
..i would learn it now itself..
Me : okay ..so at the beginning u
must understand that all the computer programs that are used are comprised of
Data Structures and algorithms ..
Techno kumar : hmmm..like?
Me : data structures actually
show what is to be processed ..and algorithms tell how it is to be processed..
Techno kumar : information systems
refer to these as data bases and
applications ..respectively .. right ??
Me : exactly ….now ..the basic
thing I that data must be logically distinct from applications ..
and there are many types of system
architecture single, two tier, three tier and finally multi-tier.
Techno kumar : ohh..but
I am getting confused what do you mean by tier ??
Me : yeaah yeaaah ..coming ..coming
..have patience techno ..single tier is the basic laptop/ desktop or server
model….do you know what is mean by a server ?
Techno kumar: yes yes I have heard about it a
lot of time..But don’t really have clarity ..
Me
: server is a computer / host to perform certain dedicated tasks or activities ..like
data base server , business application server, sales server / finance server
for companies ..etc ..
Techno kumar : gotcha ..
Me : So in the two tier companies we have
the one data server –and the application server is placed in the involved
network computers ..the benefits are high Graphical user interface as the
server is not burdened with processing activities ..understood ??
Techno kumar : yahh
getting it ..
Me : But
the thing is that wide bandwidth is required ..and maintenance is also required
..but in case of of three tier networks there is a business application server
that takes of the application load off the network computers and improves the
system by minimizing the data transfer over the networks ..
Techno kumar : so we
have to only put some sort of a user interface in the computers ..to facilitate
the process..
Me : exactly ..my
super intelligent techno …no doubt u are a good entrepreneur ….but further the
system can also be optimized by putting a separate web server along with the
business application one that would only require a web browser to be installed in
the network computers…
Techno kumar: ..hmm
..is it just like we have in the internet or other wide area networks..??
Me: yeaah …only that
in the internet there are many number of such systems linked …and simply speaking
in case of business applications the ERP is the system where the entire company
data base is put in one server ..there is a business application server ..here
the ERP ..the network companies only have the specific software in their
systems to access through a connected WAN…
Techno kumar:
hmmmm..understood …thanks Aniket ..it was really a great knowledge sharing
session ..u deserve a treat..
Me : of course ..ek
treat toh banta hi hain…so tomorrow we meet up at Arsalan ..seven pm..and dig
ourselves in the biriyani ..
Techno kumar: bye
..see ya.
